Lead Software Engineer

About Blitz

Blitz powers India's fastest e-commerce deliveries, enabling 60-minute and same-day fulfillment for brands like Decathlon, Adidas, Puma, and Purplle. Our systems use AI-driven logistics, real-time decisioning, and high-scale distributed architecture to deliver 98%+ success and 50% lower RTOs.

We're hiring a Senior Engineering Lead who focuses on solving problems, driving outcomes, and measuring impact. This is a hands-on leadership role for someone who owns delivery end-to-end, leads critical systems, and raises engineering excellence across teams.

Role Overview:

As a Senior Engineering Lead, you will:

• Lead multiple engineering initiatives from conception to measurable impact.
• Act as a hands-on IC for critical systems — design, code, review, and debug.
• Solve real business and operational problems, not just deliver requirements.
• Define success metrics for every project and validate solutions through data and monitoring.
• Improve reliability, observability, and performance across the tech stack.
• Influence engineers through technical depth, clarity, and high execution standards.

Key Responsibilities:

Outcome-Driven Engineering

• Work backwards from the problem and architect solutions tied to clear business metrics (latency, reliability, throughput, DRR).
• Measure and monitor everything — dashboards, alerts, logs, SLOs.
• Iterate continuously until expected outcomes are achieved.

Hands-On Technical Leadership:

• Write and review clean, scalable, high-quality code.
• Debug production issues quickly and lead root-cause analysis.
• Architect modular, fault-tolerant, and resilient systems.

Execution & Process Leadership:

• Plan, track, and deliver multiple engineering projects on time.
• Create strong engineering processes: CI/CD, testing, deployment checks, observability.
• Maintain a high-velocity, low-defect release culture.

Mentorship & Influence:

• Mentor engineers on system design, debugging, and problem-solving.
• Set and enforce engineering standards for quality, clarity, and measurable impact.
• Lead by example — influencing through capability, not hierarchy.

Required Qualifications:

Technical Expertise

• Graduates fromIITs, NITs or other Tier-1 colleges.
• 8–10 years of backend/full-stack engineering experience, with leadership responsibilities.
• Strong command of Java (Spring Boot), Python (Django/FastAPI), or Golang.
• Deep understanding of microservices, CQRS, DDD, and event-driven architecture.
• Experience with PostgreSQL, NoSQL, Redis/Hazelcast and opensearch.
• Familiarity with messaging systems such as Kafka, RabbitMQ, or AWS SQS.
• Comfortable with Docker, Kubernetes, CI/CD, AWS (ECS, EC2, API Gateway, Cognito).
• Knowledge of Prometheus, Grafana, distributed tracing.

Leadership Experience:

• Led multiple engineering projects to measurable outcomes.
• Strong ability to identify risks early and design preventive systems.
• Experience mentoring engineers and raising technical standards.
• Able to balance hands-on execution with architecture and planning.

Mindset & Culture Fit:

• Outcome-first, not output-first.
• Thinks in metrics and root causes, not assumptions.
• Ownership-driven — uptime, reliability, and system health matter personally.
• Thrives in fast-paced, high-accountability environments.

Bonus Skills:

• Experience with AI-assisted development or AI agents.
• Background in logistics, supply chain, fintech, or high-scale transactional platforms.
• Expertise in performance engineering or incident management.

Why Blitz

• Contribute to systems powering millions of deliveries and decisions daily.
• Be part of a culture that values speed, clarity, reliability, and impact.
• Work on real-world, high-scale challenges that deliver immediate measurable outcomes.
• Shape India's next-generation commerce and logistics ecosystem.
